We have a relatively new home that we contracted to have built. We have a problem with our garage door when using our electric opener. The door is a double wide door. During low temperatures (below freezing) the door only opens about 8 inches to 16 inches before stopping when we activate the opener. All other times it works flawlessly. We either have to start closing and immediately push the open button before it is down to get it to fully open or apply a bit of upward lifting pressure to the handle after hitting the opener to get it up. This kind of defeats the purpose of having an electric opener installed especially in the cold weather. Our original contractor is a deadbeat so we cannot turn to him. I know this is a contraction/expansion problem and probably just a minor adjustment or something easy but am a little lost on what exactly we need to do.
Once they have your money service does seem to take a down turn. But to your problem. Do you have the installation manual, if not try download it from the web or call the manufacturer. They should have left you with it but who knows. My first suggestion is pull the release cord on the garage door opener when you are having the problem. Now you should be able to open and close the door by hand with little difficulty. If not, the door it self was not installed well and it could be a number of issues from the spring being set wrong to the door binding some where. Possibly you will see where it binds, If this is the case inform your builder and he might actually do something as he can now most likely harp on a sub. If the door does open and close easily, the open pressure may be too low. Your manual will tell you how to change this (recommended approach), but all the ones I've seen have a two small dials at the back of the garage door opener numbered 1-10 or similar. One for Open max pressure, one for close max pressure. Note these are for safety to minimize the amount of pressure and minimize the possibility of injury or damage. If you increase the open pressure by half an increment and try door again. If you have to turn it excessively the problem might be else where with the opener.
